Question

Explain 20 please

100 Age 591 Questions 17 - 21 are based on the graph to the right. This graph describes the age structure of a population 96-991 17. The fraction of the youngest age class is 90-941 a. The largest in the population 85-891 80-841 b. The smallest in the population 75-79 C. Larger than that of middle age classes (30 - 60 70-74 85-89 years old) 60-64 d. Smaller than that of middle age classes (30 - 60 55-59 50-54 years old) 45-49 18. The fraction of old (>80) females is 35-39 a. Larger than the fraction of old males 30-34 b. Equal to the fraction of old males 25-29 20-24 C. Smaller than the fraction of old males 19. What does it mean 10-141 a. That females have higher longevity b. That males have higher longevity 6 C. That females have higher fecundity d. That males have higher fecundity e. That males and females have the same longevity Male 20. What does it indicate regarding the general age of the population a. It is a relatively young population b. It is a relatively middle-aged population C. It is a relatively old population 21. What does it suggest regarding the growth pattern of the population a. Population grows exponentially b. Population stable C. Population is declining 5 4 3 1 2 3 4 5 6 2 1 0 Population Female

Answer 1

Explanation of ques 20.-in the above graph we seen the fraction of longetivity of male and female according to their age ,above given graph clearly shown that the growth rate and longitivity rate of middle aged group whether they maybe male or female is higher than any other age group ,so the correct answer for ques 20 is b( it is relatively of middle aged population).
